Abstract
Stimulated Raman scattering of an ultra-intense laser pulse in plasmas is
studied by perturbatively including the leading order term of the
Landau-Lifshitz radiation reaction force in the equation of motion for plasma
electrons. In this approximation, radiation reaction force causes phase shift
in nonlinear current densities that drive the two Raman sidebands (anti-Stokes
and Stokes waves), manifesting itself into the nonlinear mixing of two
sidebands. This mixing results in a strong enhancement in the growth of the
forward Raman scattering instability.
